To. dlll whom it may concern:

Be it known that I, LEWIS STEELMAN, a citizen of the United States, residing at Millville, in the county of Cumberland and State of New-Jersey, have invented a new and use ful Glass-Delivering Machine, of,which the following is aspecification. v

This invention has relation to "machines for deliveri I "glass and consists in the novel construbtioixnd arrangement of its parts as The object of the invention is to provide a machine especially adapted to be used to as for instance bottle stoppers and other articles. The machine is designed to be used in combination with a melting tank having pass therefrom in predetermined quantities. The furnace is provided'with a hood which is located over the metal outlet and a heatunderthe hood at a desired degree or temperature. A rotatable table is located under the hood and-means are provided for raising and lowering the said table; Theare connected to each" other by a trough.

In the accompanying drawings :-,Figure lis a side elevation of the machine for delivering glass, parts being shown in section. Fig. 2 is a top plan view of the said machine. parts being shown in section. Fig. 3 is a bottom plan view of the top of the pot carry ing table forming a part of the machine. Fig. 4 is a perspective view of one of the sectional view of one ofthe pots. As illustrated in the accompanying drawings the tank-1 is provided in the vicinity of its discharge side with a vertically disposed metal passage' way 2. A valve 3 is arranged to close against the upper end of the said passage-way and-is attached to the lower end of a stem 4 which passes up through the top of the furnace 1. A lever 5 is fulcrumed'upon the top of the furnace and one end thereof is pivotally connected to the upper end of the stem 1. The upperv end of a rod 6 is connected to the other'end' of the lever 5 and said rod 6 is located exteriorly of the furnace 1 and extends down along the same and is provided at its lower end with a laterally disposed portion A GLAss-nnnivnnme MACHINE.

port and that end of the lever 5 which is p a ly connected with the said rod 6.

The spring 8 is under compression with'a tendency to hold that end of the lever 5 in? an elevated position. By this means. the r lever 5 is normally held in such position so 9' passes through the vertical wall 0f the furnace 1 and has its inner end-located the vicinity of'the upper end of the passage 2 in the said tank and the outer end ofthe 7 said trough 9 is disposed over a. series-of pots hereinafter to be described. i A standard or base 10 is locatedexteriorly 5 of the tank 1 and beyond the outer or'deliv- W end of the spout 9. An externall ym 15* ery threaded post 11 is arranged to slide vertically within the standard 10 and a ring 12 I is screwthreaded upon the said post and bears against the upper endof the'said standard. The ring 12 is provided at inter vals with handles 13 whereby the said ring may be rotated about the axis of the post 11 and when this is done the said post win-be movedvertically in the standard 10." platform 14 is fashioned upon or mounted upon the upper end of the post 11 and is provided upon its upper surface with a ball" race which receives bearing balls 15.- A table 16 is provided upon its under side with 5 a race which-rests upon the said bearing:

ducting material 17 is mounted'upon thew-s balls 15. A stone or other non-heat-conupper side of the table 16 and a series'ofw" pots 18 are concentrically arranged upon the upper surface of the stone 17, The said pots 18 are held in properv spaced relation and are connected together by means of: T

troughs 19 which connect at their ends with. recesses-20 provided at the ends of the said pots 18.. A hood 21 is supported upon the furnace 1 and is located over the delivery. end of the spout 9 and a burner 22 prefer-f, ably'of the hydro-carbon type has, its dis charge end arranged to project a flame through an opening 23 provided in thetop)... w

of the hood 21 and directly above those pots 18 which are inthe vicinity of the delivery end of the spout 9. The table 16 is provided upon its under side with a series of lugs 24:

into the path of movement of which the laterally disposed end portion 7 of the rod 6 projects. The said table 16 is also provided upon its under side with a concentrically arranged set of gear teeth 25 which mesh with a gear Wheel 26 journaled upon a suit- "1 able support and having a wrist pin 27 to one end of which aconnecting rod 28 is pivotally attached. The other end of the said connecting rod 28 is attached to a piston rod 29 which is arranged to reciprocate in a cylinder 30 mounted adjacent the standard 10.

tion of the table 16 and is also located over- The hood 21 is located over the major porin a molten state and that through the gear wheel 26 meshing with the gear teeth 25 upon the under side of the table 16 the said table and those parts mounted thereon are rotated under the hood 21. It is of course understood that the gear wheel 26 is rotated by means of the connecting rod 28 and piston rod 29 operating in the cylinder 30. The operation of the piston within the cylinder 30 is intermittent and is caused by an operator or attendant and as such controlling means form no part of the present invention they are omitted in the present illustration and description. As the table 16 rotates upon the bearingballs 15 the pots 18 are successively carried under the delivery end of the spout 9. deliverv end of the said spout the lugs 24 successively come into contact with the laterally disposed lower end portion 7 of the rod 6 and the said rod 6 moves in a downward direction against the resistance of the spring 8. This movement on the part of the rod Greeks the lever 5 upon its fulcrum as the valve stem 4 is moved in a vertical direction which litts the valve 3 from the upper end of the metal passage 2 provided in the tank 1. When the valve 3 moves away from the upper end of the passage the metal is free to {low from the said passage along'the spent 9 and into that trough 8 whi h is located below the delivery end of the said spout. As the table 16 continues in its rotary movement the lug 24 which has inst been in engagement with the laterally disposed portion 7 of the rod (1 moves beyond the said portion 7 and the tension of the spring 8 then comes into plav and lifts the rod ti' wherehy the operation of the lever 5 and the valve stem 4 and valve 3 is reversed .and the said valve 3 is closed down against the upper end of the metal passage 2 in the tank 1 and the flow of the metal As the pots move under thefrom the tank to the trough 9 is interrupted. This operation is repeated throughout the entire serles of pots and at the same time a jet of flame is permitted to escape from the burner 22 through the opening 23 in the top of the hood 21 and this flame keeps the contents of the pots at a desired temperature. Anyexcess of metal which is received by any one of the pots 18 may flow through the opening'QO of the said pot and along the trough 19 into one or more of the adjacent pots and thus means is provided. for preventing the pot from overflowing. The slab of stone 17 or an equivalent material prevents the table 16 and the parts located thereunder from becoming unduly heated.

The'object in providing table 16 with means for vertically adjusting it is to accommodate said table to pots of different heights. a

It is to be understood thatv the machine herein described is more particularly designed for use in connection with gathering and molding mechanism such as constitutes the subject matter of an application filed by me on March 31. 1911, Serial No. 618,155, said application being a division of the present application.
